To aZZ 1071 0122 it may concern: show an interior construction. Fig. 3shows Be it known that l, ALvAN A. SIMONDS, a the shaft employed in oneform of my interior citizen of the United States, residing at Daysupport. 55

In the-drawings Myinvention relates to the class of paperthese doors are shown as hingedat a a to a driers in which the paper is passed through central portionof the top of the tube; but it 6 a narrow box and is subjected to theaction of is obvious that these doors or movable covers [5ahighly-heated blast of air therein. \Vhere may constitute the entiretop of the tube or the air for drying is admitted at both top and box,and they may be hinged to open outbottom of the box, and where the paperweb wardlyinsteadof in the manner shown,though acted upon is ofconsiderable strength and such construction is not thoughtto possess thethickness, no support for the paper is readvantages of a cover openingtoward the cen- 20 quired within the box, as the current of air ter.

Inthat class, to have means wherebythe opera stead of the swivel-joint being located in a 8 tor may haveaccess to the interior of the portion of the pipe parallel to the pipedis- 5 tube for the introduction of the paper web charging into thedrier,it might be in the per and to assist in the passage through thebox tion a", which is at right angles thereto. The where the web isbroken or torn. part c of the top is not connected to any other Theobject of my present invention is to portion of the top or with the box;but being provide aconstruction which will give ready attached to thepipe 0 by turning the pipe 0 o access to the interior of the tube andwill furupon its swivel at c, the top 0 is lifted and nish asatisfactory support for a thin web of turned away from the end of thebox, giving paper within the same. One form of conthe operator fullaccess thereto. struction for accomplishing these results is In Fig. 1 Ihave shown in section two differshown in the accompanying drawings, anddcent constructions for supporting a thin web of 5 scribed in thisspecification, and the invention paper and directing the air against thesame. is fully pointed out in the claims. One of the constructionsconsists of a small In the drawings, Figure 1 is a view of a roller, D,journaled in the side of the box or portion of a drier constructed inaccordance tube, This roller is of less diameter than the with myinvention, the drying tube or box and distance from the path of thepaper web to 50 the parts connected therewith being shown in the lowerside of the box. This admits of a section. Fig. 2 is a plan View of thesame passage of air beneath the same; but as the with a portion of thetop broken away to air in such case would be directed away from 'tion.

tube beneath the paper web may be directed against it, I place over theshaft D a guide, (2,

the paper, I place a guide, d,.inclining from the bottom upward towardthe paper to direct the air against the same. In the other constructionshown I employ a shaft, D, which is provided at intervals with narrowfixed collars D. The diameter of these collars is equal to thedistancefrom the path of the paper web to the lower'side of the box,and, the paper web coming in contact with the upper part of thesecollars, is supported in its proper posi- In order that the air admittedto the consisting of asheet of rigid material provided with slots oropenings through which the collars I) may project. The portion of thisguide between the slots is supported just above the shaft D, and itsedges arebent downward and attached to the bottom of the tube or box A.Instead of making D of a sheet of thin material, it may be made of asolid material with openings for the shaft D and recesses for thecollars D The operation of the construction shown and described it isthought will be clearly understood from the foregoing description. Inintroducing the thin web of paper the pipe 0 is turned, giving theoperator access to the interior of the drier at that end. The web beingintroduced through the narrow slot, the operator returns the pipe 0 toits place, and, opening one of the doors a, carries the web through thebox to the rolls on the other side. The web, coming in contact with thecollars D of shaft D, is supported in proper position during itstraverse through the box or drier, while the air admitted to the underside of the paper web will have a sufficient space to pass beneath thepaper and will be directed against the same. It will be no ticed thatthe guide (1, when made of sheet material, is made to extend to bothsides of the shaft D merely for convenience and to give it rigidity.Such guide might be divided in the center along the line of the shaftand the part farthest from the air-inlets dispensed with, the inclinedportion rising from the bottom of the box to the top of the shaftbetween the shaft and the air-inlets being the only part necessary toeffect the result desired.

It will be noticed that in the description of the operation herein thepaper web is spoken of as moving from the end provided with a narrowslot toward the other 'end. I do not desire to limit myself to such amovement of the paper, but the paper, if desired, may be passed throughthe drier in a reversed direction.

I have shown anddescribed a drier consisting of a narrow box or tubehaving air-inlets at the top and bottom at one end and an opening thefull size of the tube at the other end; but this construction is notclaimed herein, as it forms the subject'matter of my application, No.202,119, now pending. I

\Vhat I claim, and desire to secure by Let- 1. The combination,with abox or tube having an opening at each end for the passage of the paperweb therethrough, of an air-inlet in the top near one end of said box,and doors or lets at top and bottom near one end, of a support for thepaper web, consisting of a roller having a space. beneath the same and aguide inclining from the bottom of the tube upward toward the paper,substantially as described.

3. The combination, with the tube or box having openings at each endforthe passage of a paper web therethrough, air-inlets at top and bottomnear one end of said box, a sup-.

porting-roll for the-paper web, consisting of a shaft provided withrigid collars and an airguide on the side nearest the air-inletsinclining from the bottom of the box to the topof the shaft between thecollars, substantially as described.

4. The combination, with the tube or box having openings at each end forthe passage of a paper web therethrough, of a support for the web withinthe box,consisting of shaft D, provided with collars D and the slottedguide (1, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
